why wont this work?

local p=game:GetService("PathfindingService")
p.EmptyCutoff=0
spawn(function()
    local torso,humanoid = script.Parent:WaitForChild("Torso"),script.Parent:WaitForChild("Humanoid")
    torso.Touched:connect(function()
        wait(math.random())
        humanoid.Jump = true
    end)
    local walk;
    walk=function()
        local target = script.Parent.Targe.Value.Torso
        local path=p:ComputeSmoothPathAsync(torso.Position,target.Position,500)
        if path.Status.Name == "Success" then
            local points = path:GetPointCoordinates()
            for i,point in pairs (points)do
                local part,P=workspace:FindPartOnRay(Ray.new(point,Vector3.new(0,-10,0)))
                if part then
                    point = p
                    points[i] = p
                end
            end
            local distance;
            for i=1,#points do
                local point = points[i]
                humanoid:MoveTo(point)
                local jump;
                if point.Y>=torso.Position.Y-1.5 then
                    humanoid.Jump = true
                    jump=humanoid.Changed:connect(function()
                        humanoid.Jump = true
                    end)
                end
                local reached=humanoid.MoveToFinished:wait()
                if jump then
                    jump.Disconnect()
                end
                if not reached then
                    return walk()
                end
            end
        else
            humanoid:MoveTo(torso.CFrame*Vector3.new(0,0,5))
            humanoid.MoveToFinish:wait()
        end
        return walk()
    end
    walk()
end)

it is a pathfind script. i use a different model to make my own but this does not work. in the output this error pops up. 00:30:36.619 - Unable to cast Instance to Vector3 00:30:36.619 - Script 'Workspace.Police.Script', Line 25 - local walk 00:30:36.619 - Script 'Workspace.Police.Script', Line 47 00:30:36.620 - Stack End can someone help me please
